Leaching Potential of Per- and Polyfluoroalkyl Substances from Source Zones with Historic Contamination of Aqueous Film Forming Foam - a Surfactant Mixture Problem
Highlights• Compound specific leaching of PFAS from historically AFFF contaminated soil• Short-chain PFAS decreased rapidly in concentration• Long-chain PFAS showed an initial increase in concentration• Residual PFAS levels in the soil are high in low DOC levels in leachate
